Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
4,4'-Dibromo-2,2'-bis(triisopropylsilyl)-5,5'-bithiazole (CAS 1223559-98-5), molecular formula C24H42Br2N2S2Si2 and molecular weight 638.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4'-Dibromo-2,2'-bis(triisopropylsilyl)-5,5'-bithiazole (C24H42Br2N2S2Si2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
